To convert other file formats to the "Uncompiled Font Project" file type, you need software like FontLab Studio or a similar tool.
About VFB files
A .VFB file is most commonly a Vector Font Binary project created by FontLab Studio. These files store uncompiled typeface designs, including vector outlines, metrics, hinting, and kerning data. A smaller percentage of .VFB files function as Calendar Free/Busy data, used by Microsoft Outlook and Horde Kronolith to broadcast user availability on a network. The FontLab .VFB format is highly proprietary and closed-source. A major disadvantage is that these files cannot be installed directly as system fonts and normally require an expensive software license to edit. The calendar variant is similarly limited, often acting as a legacy method for Exchange servers. Users typically need to convert font .VFB files to standard formats like .TTF (TrueType) or .OTF (OpenType) so they can be installed on Windows or macOS. Calendar data should ideally be converted to .ICS for modern compatibility. Because the font data structures are undocumented and complex, standard online converters fail to process them. Often, only the original FontLab software or the open-source FontForge can properly read or export the bezier curves. Drag and drop your file to convert.guru to see what it is and convert it if supported. While compiling a font requires dedicated software, convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your VFB file, detects the exact format, and lets you read the text inside.
If you want to convert VFB file to TTF, OTF, WOFF, WOFF2, EOT, SVG, BDF, PCF, FNT, FON, PFM or AFM, you can use FontLab Studio or similar software from the "Source Font & Calendar Data" category. In the File menu, look for Save As… or Export….
To convert UFO, WOFF, PFB, GXF, AFM, F3F, SFD, WOFF2, PSF, TTF, TXF or OTF files to VFB, try FontLab Studio or another comparable tool in the "Source Font & Calendar Data" category.
The VFB Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our VFB converter.
